kOS: Scriptable Autopilot System

# v1.1.3.0 (for KSP 1.3) Bug Swatting Release

For this release we instituted a rule partway through that only bug fixes
should be allowed (some of the first few changes were enhancements rather
than bug fixes, but after that, its all bug fixes). This was in a vain
hope that doing so would get a release out faster than normal.

### BREAKING CHANGES

(Can't think of any.)

### NEW FEATURES
* Terminal input using any Unicode character, not just ASCII.
(Technically not a new feature, but a bug fix to a feature
from the previous version, but since the bug made the feature
never work *at all* in the past, it feels like a new feature).
[pull request](https://github.com/KSP-KOS/KOS/pull/2062)
* New StartTracking suffix for "unknown objects" (asteroids).
[pull request](https://github.com/KSP-KOS/KOS/pull/2077)

### BUG FIXES
* A large refactor of how the various flight control methods track
which vessel they control. This appears to have fixed a lot of
bugs where kOS lost the ability to control the ship unless
you reloaded the scene. (After a docking, undocking, staging,
vessel switch, or scene switch, this would sometimes happen,
but not consistently enough to be easy to debug).

[pull request](https://github.com/KSP-KOS/KOS/pull/2063)
* Program aborts caused by external events such as poweroff,
shutdown, or control-C no longer leave garbage behind in
memory still hooked into parts of kOS.
[pull request](https://github.com/KSP-KOS/KOS/pull/2019)
* Documentation now more explicitly mentions how SAS and lock steering
fight with each other.
[pull request](https://github.com/KSP-KOS/KOS/pull/2111)
* Documentation for GUIskin:add() was wrong. Fixed.
[pull request](https://github.com/KSP-KOS/KOS/pull/2098)
* The waypoint() constructor used to fail on waypoints which
were *not* part of a cluster yet were named as if they
were part of a cluster anyway ("my waypoint Alpha",
"my waypoint Beta", "my waypoint Gamma", etc). This doesn't
happen in stock, but does happen with several mods that use
ContractConfigurator. kOS will now deal with such waypoints.
[pull request](https://github.com/KSP-KOS/KOS/pull/2093)
* Documentation that claimed obsoleted TERMVELOCITY still
exists has been removed or edited.
[pull request](https://github.com/KSP-KOS/KOS/pull/2067)
* Trying to examine the NoDelegate object no longer causes
nullref error.
[pull request](https://github.com/KSP-KOS/KOS/pull/2082)
* Equality operator ( == ) when comparing a Path to a Path now
fires off correctly.
[pull request](https://github.com/KSP-KOS/KOS/pull/2089)
* GUI's ONRADIOCHANGE callback hook now no longer depends
on the existence of an ONTOGGLE hook to fire off.
[pull request](https://github.com/KSP-KOS/KOS/pull/2088)
* Compiler no longer creates incorrect opcodes for indexed
collections used as arguments to a function call that's
on the lefthand side of an assignment statement.
[pull request](https://github.com/KSP-KOS/KOS/pull/2079)
* Font resizing in scripts no longer causes the terminal to mangle
its size and width/height character count
[pull request](https://github.com/KSP-KOS/KOS/pull/2081)
* Signal delay progress bar (when using Remote Tech) will now resize
properly when you have a nonstandard sized terminal window.
[pull request](https://github.com/KSP-KOS/KOS/pull/2076)
* Compile command now works properly when run from the interpreter.
[pull request](https://github.com/KSP-KOS/KOS/pull/2071)
* Vessel:isDead working properly now
[pull request](https://github.com/KSP-KOS/KOS/pull/2070)
* Stretching the terminal to a large size no longer causes
the rounded corner to obscure text in the window.
[pull request](https://github.com/KSP-KOS/KOS/pull/2060)
* Full unicode keyboard and file save support was getting
mangled by wiping out the high byte leaving only the 8-bit
ASCII part left. Fixed.
[pull request](https://github.com/KSP-KOS/KOS/pull/2062)
* Toolbar Panel setting changes no longer require there to
exist a kOS part loaded into the scene.
